I just picked up a 440 out of a truck. The engine is a 1975 and is in great shape, never molested and had a documented 56k on it. Upon tear down I noticed how clean the engine was. The hone marks on the cyls still look fresh. Unfortunately from what I've read the 70's bb are dogs. Low compression and poor performing cams. I'd like to do a "low budget" build and get some more power out of this thing. Crank bearings and journals are perfect as are the cyls so blocks getting cleaned, new bearings getting installed, new rings, reuse pistons, more aggressive cam and aluminum heads and intake. I found a set of new heads with 72cc combustion chambers for $1000 on ebay. I'm guesstimating around 11:1 compression with these heads. What so you guys think? Not trying to make a race engine but would like more power. This is going I be a cruiser but I'd like to get on it once in a while, no track time though. Thx
